This letter encloses the original decode of the Zimmermann Telegram as deciphered by a Mr. Bell of the American Embassy in London and an official in the Admiralty Office of the British Government. Mr. Bell used the encoded message received at the telegraph office in Washington, DC and deciphered it using cipher 13042, which was previously retrieved during World War I by the British Government. This decode of the Zimmermann Telegram helped to prove that the contents of the telegram were true and that it was not a hoax sent by belligerents.
